RESUMO

BACKGROUND AND OBJECTIVES: Sarcopenia is common in hemodialysis patients. This study examined whether the anabolic steroid oxymetholone improves muscle mass and handgrip strength in hemodialysis patients and possible mechanisms that might engender such changes. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: Forty-three eligible hemodialysis patients were randomly assigned to ingest oxymetholone or placebo for 24 weeks. Body composition, handgrip strength, and quality of life were measured during the study. Muscle biopsies were performed and analyzed for mRNA levels for myostatin, IGF-I, IGF binding proteins, and myosin heavy chains and protein expression. Muscle fiber types and diameter were assessed by reduced nicotinamide-adenine dinucleotide staining. RESULTS: There was a significantly greater increase in fat-free mass and handgrip strength and decrease in fat mass in the oxymetholone compared with the placebo group. Moreover, compared with baseline values, patients given oxymetholone exhibited an increase in fat-free mass, handgrip strength, physical functioning scores, and type I muscle fiber cross-sectional area and a decrease in fat mass, whereas patients receiving placebo did not undergo changes. There was a significantly greater increase in muscle mRNA levels for myosin heavy chain 2×, IGF-I, and IGF-II receptor with oxymetholone treatment than placebo. Liver enzyme rose significantly in the oxymetholone group, but the number of values greater than three times the upper limit of normal were not different between these groups. CONCLUSIONS: In hemodialysis patients, ingesting oxymetholone was associated with an increase in fat-free mass, handgrip strength, and muscle mRNA levels for several growth factors and a decrease in fat mass, but it also induced liver injury.

RESUMO

OBJECTIVES: To determine the efficacy of oxymetholone, an androgenic steroid, in combination with rHuEPO on hematologic and muscle mass in CAPD patients. METHODS: A double-blinded, placebo-controlled experimental study was conducted for 6 months and 24 CAPD patients were divided into two groups. The treatment group (n = 11) received rHuEPO plus oral oxymetholone (50 mg/tablet twice daily). The placebo group (n = 13) received rHuEPO plus a placebo twice daily. The evolution of the patients' hematologic parameters and the impact of the drugs on their muscle mass were evaluated. RESULTS: After 6 months of therapy, hematocrit and hemoglobin values of the treatment group were significantly different from those of the placebo group (38.1 ± 1.0% and 32.8 ± 0.9%, p = 0.001; 12.9 ± 0.3 g/dl and 11.0 ± 0.3 g/dl, p = 0.001 for hematocrit and hemoglobin, respectively). The increase in hematocrit and hemoglobin values observed in treatment group was statistically greater than those of the placebo group (p < 0.01). After 6 months, none of anthropometric parameters, albumin, protein or lean body mass levels, were significantly different from baseline in the placebo group. Conversely, most of the anthropometric parameters, albumin and lean body mass levels were significantly increased in the oxymetholone group (p < 0.05). The mean weight of subjects in the oxymetholone group changed from 63.82 ± 2.71 to 67.02 ± 3.26 kg (p = 0.001). The subjective global assessment score for 7 patients in the treatment group (63.6%) changed in a positive manner. A rise in liver enzymes was the main side effect observed in the treatment group. CONCLUSIONS: Oxymetholone significantly enhances the erythropoietic effects of rHuEPO and improves the nutritional status of CAPD patients. However, significant increases in liver enzymes need to be monitored closely.

RESUMO

AIMS: To investigate the beneficial effects of oral oxymetholone on IR in hemodialysis (HD) patients by increasing skeletal muscle function and stimulating myocyte glucose uptake and metabolism. METHODS: In a randomized, controlled double-blind study, 44 patients were randomly assigned to one of two groups: a treatment group that received oxymetholone 50 mg orally twice daily and a control group that received placebo twice daily for 24 weeks. IR was calculated by using HOMA, and dual-energy X-ray absorptiometry was used to determine body composition. All patients were encouraged to walk at least one kilometer daily and were monitored by the Barthel index activity score. RESULTS: 25 men (57%) and 19 women (43%) were studied. 23 subjects were in the control group, and 21 subjects were in the treatment group. The mean age of patients and the duration of dialysis were 43.5 +/- 9.9 years and 92.8 +/- 37.8 months, respectively. After treatment, the HOMA index and body fat mass (FM) were significantly decreased in the treatment group compared to those in the control group (10.8 +/- 16.4 vs. 3.1 +/- 4.5; p < 0.05 and 1.73 +/- 2.77 vs. 0.40 +/- 1.12 kg; p < 0.05, respectively). Concurrently, the mean change of fat free mass (FFM) in the treatment group was higher than that in the control group (3.24 +/- 1.74 vs. 0.65 +/- 1.21 kg, p < 0.05). Two patients in the treatment group experienced an elevation in serum liver enzymes (9.52%). CONCLUSION: HD patients treated with short-term oral oxymetholone showed an increase in insulin sensitivity when compared to the placebo group, and this effect depended on changes in FFM and FM.

RESUMO

Oxymetholone is a 17alpha -alkylated anabolic-androgenic steroid. This drug can stimulate bone marrow cells and increase the blood cells in the peripheral blood vessels. It has been used for the treatment of anemia caused by low red cell production. Since oxymetholone has hematopoietic effect, we studied radioprotective effects of this drug in mice. In this study, we determined percentage of survival, dose-reduction factor (DRF) and hematological parameters in irradiated mice which treated with or without oxymetholone. Oxymetholone administrated at different doses 80, 160, 320, 640 mg/kg by gavages at 24 h before 8 Gy gamma irradiation. At 30 days after treatment, the following percentage of animals survival in each group was as: 80 mg/kg, 50%; 160 mg/kg, 50%; 320 mg/kg, 55%; 640 mg/kg, 75% and vehicle, 15%. Percentage of survival increased in all of treated groups statistically compared with irradiated-vehicle group. In the groups treated by oxymetholone, maximum protection was realized at 640 mg/kg. In order to calculate the DRF for oxymetholone, mice were exposed to whole-body gamma irradiation with dose ranges between 5.83 and 11.23 Gy. The probit line for oxymetholone-treated mice was shifted to the right with a DRF of 1.14. In mice exposed to whole-body gamma-irradiation (4 Gy), an oral administration of 640 mg/kg oxymetholone ameliorated radiation-induced decreases in circulating platelets and erythrocytes, but had a less effect on total number of WBC. These results demonstrate that oxymetholone stimulates myelopoiesis and thrombocytopenia and enhances survival in mice after ionizing radiation.

RESUMO

Previous studies by the authors have shown voluntary intracerebroventricular (icv) testosterone self-administration in hamsters (Mesocricetus auratus). Here, the authors compared icv self-administration of 4 anabolic steroids (drostanolone, nandrolone, oxymetholone, and stanozolol) at 0.1, 1.0, and 2.0 microg/microl, each for 8 days. Males (n=8/group) showed the highest levels of operant behavior for injectable steroids (drostanolone, nandrolone) compared with orally active androgens (oxymetholone, stanozolol). For nandrolone, responses on the active and inactive nose-pokes averaged 22.3 +/- 4.6/4 hr and 10.7 +/- 2.0/4 hr, respectively. Responding for drostanolone was similar. Males self-administering oxymetholone or stanozolol did not prefer the active nose-poke. These data demonstrate that injectable androgens are more reinforcing than oral steroids.

RESUMO

Anabolic androgenic steroids (AAS) are used illicitly at high doses by bodybuilders. The misuse of these drugs is associated with serious adverse effects to the liver, including cellular adenomas and adenocarcinomas. We report two very different cases of adult male bodybuilders who developed hepatocellular adenomas following AAS abuse. The first patient was asymptomatic but had two large liver lesions which were detected by ultrasound studies after routine medical examination. The second patient was admitted to our hospital with acute renal failure and ultrasound (US) studies showed mild hepatomegaly with several very close hyperecogenic nodules in liver, concordant with adenomas at first diagnosis. In both cases the patients have evolved favourably and the tumours have shown a tendency to regress after the withdrawal of AAS. The cases presented here are rare but may well be suggestive of the natural course of AAS induced hepatocellular adenomas. In conclusion, sportsmen taking AAS should be considered as a group at risk of developing hepatic sex hormone related tumours. Consequently, they should be carefully and periodically monitored with US studies. In any case, despite the size of the tumours detected in these two cases, the possibility of spontaneous tumour regression must also be taken in account.

RESUMO

BACKGROUND: Despite highly active antiretroviral therapy (HAART), chronic involuntary weight loss still remains a serious problem in the care of HIV patients due to various alterations in energy metabolism and endocrine regulation. Previous studies in HIV-positive men undergoing androgen replacement therapy or treatment with recombinant growth hormone (rGH) have shown partial restoration of lean body mass (LBM), but these treatments have largely not been sufficiently studied in eugonadal individuals. METHOD: A double-blind, randomized, placebo-controlled trial of 89 HIV-positive eugonadal women and men with wasting assigned to the anabolic steroid oxymetholone (50 mg bid or tid) or placebo for 16 weeks was performed. Body weight, bioimpedance measurements, quality of life parameters, and appetite were analyzed. RESULTS: Oxymetholone led to a significant weight gain of 3.0 +/- 0.5 and 3.5 +/- 0.7 kg in the tid and bid groups, respectively (p <.05 for each treatment versus placebo), while individuals in the placebo group gained an average of 1.0 +/- 0.7 kg. Body cell mass (BCM) increased in the oxymetholone bid group (3.8 +/- 0.4 kg; p <.0001) and in the oxymetholone tid group (2.1 +/- 0.6 kg; p <.005). Significant improvements were noted in appetite and food intake, increased wellbeing, and reduced weakness by self-examination. The most important adverse event was liver-associated toxicity. Overall, 43% of patients in the tid group, 25% of patients in the bid oxymetholone group, and 8% in the placebo group had a greater than 5 times baseline increase for ALT, AST, or gamma GT, while other adverse events were not increased over placebo. CONCLUSION: Oxymetholone can be considered an effective anabolic steroid in eugonadal male and female patients with AIDS-associated wasting. The bid (100 mg/day) regimen appeared to be equally effective to the tid (150 mg/day) regimen in terms of weight gain, LBM, and BCM and was associated with less liver toxicity.

RESUMO

To determine whether oxymetholone increases lean body mass (LBM) and skeletal muscle strength in older persons, 31 men 65-80 yr of age were randomized to placebo (group 1) or 50 mg (group 2) or 100 mg (group 3) daily for 12 wk. For the three groups, total LBM increased by 0.0 +/- 0.6, 3.3 +/- 1.2 (P < 0.001), and 4.2 +/- 2.4 kg (P < 0.001), respectively. Trunk fat decreased by 0.2 +/- 0.4, 1.7 +/- 1.0 (P = 0.018), and 2.2 +/- 0.9 kg (P = 0.005) in groups 1, 2, and 3, respectively. Relative increases in 1-repetition maximum (1-RM) strength for biaxial chest press of 8.2 +/- 9.2 and 13.9 +/- 8.1% in the two active treatment groups were significantly different from the change (-0.8 +/- 4.3%) for the placebo group (P < 0.03). For lat pull-down, 1-RM changed by -0.6 +/- 8.3, 8.8 +/- 15.1, and 18.4 +/- 21.0% for the groups, respectively (1-way ANOVA, P = 0.019). The pattern of changes among the groups for LBM and upper-body strength suggested that changes might be related to dose. Alanine aminotransferase increased by 72 +/- 67 U/l in group 3 (P < 0.001), and HDL-cholesterol decreased by -19 +/- 9 and -23 +/- 18 mg/dl in groups 2 and 3, respectively (P = 0.04 and P = 0.008). Thus oxymetholone improved LBM and maximal voluntary muscle strength and decreased fat mass in older men.

RESUMO

We report a rare case of hepatic adenomas (HA), in a 20-year-old Japanese girl treated for 6 years with anabolic androgens for aplastic anemia. In a review of the world literature using computer MEDLINE search, we found only 17 cases of androgen-induced HA published between 1975 and 1998 in the English-language literature. The patient was referred to us because of liver lesions detected during a follow-up examination for familial adenomatous polyposis. After being diagnosed with aplastic anemia at 14 years of age, she had been treated with oxymetholone (30 mg/day) for 6 years. Laboratory evaluation revealed normal liver function. Ultrasonography (US) and computed tomography (CT) demonstrated multiple liver lesions. Histopathological examinations of biopsied specimens from the liver tumor showed HA. After the patient was diagnosed with HA, oxymetholone was tapered off. Patients taking androgenic-anabolic steroids should be carefully monitored with US and CT and tumor markers should be measured. This report may be helpful in identifying the population who is at risk of developing hepatic sex hormone-related tumors.

RESUMO

AIDS: Promising new developments involving four anti-HIV agents are described. HE2000, a new treatment for end-stage disease, may interrupt HIV's entry into cells, thus preventing damage. Norvir-SGC, a new gel-capsule form, available June or July 1999, should aid in eliminating the foul taste of the drug, and lessen the chance of diarrhea. New studies of Anadrol-50, a drug promoting lean muscle growth, suggest it is not metabolized by the same liver pathway as most drugs used to treat HIV. Therefore, it probably will not interact with drug "cocktails" or highly active antiretroviral therapy regimens. Research indicates that hydroxychloroquine, a drug for managing rheumatic illness and lupus, may disrupt HIV's attachment to key immune cells including macrophages. However, clinical trials are not being done with this inexpensive drug in favor of using more expensive drugs.^ieng

RESUMO

AIDS: Oxandrin and Anadrol-50 are both oral anabolic steroids approved by the Food and Drug Administration (FDA), and they are competing for market share in the world of HIV treatments. Both are described as "open label" drugs and as such, are prescribed to reverse wasting and metabolic complications associated with HIV. Anadrol-50 is among the most potent steroids ever developed for building muscle, and study participants gained an average of 14.5 pounds for each 100 pounds of weight. Early studies indicate minimal side effects with liver toxicity, but that is not a certainty since oral anabolics are known for liver toxicity. Many studies have documented Oxandrin's safety and effectiveness in treating HIV wasting. It is metabolized in the kidney and acts without the masculinizing side effects associated with other steroids, such as Anadrol-50. One study showed an average weight gain of 24 pounds following 8 months of treatment. Oxandrin is the best choice for those at the earliest stages of AIDS wasting syndrome. However, when a more aggressive treatment is necessary, Anadrol-50 is stronger, less expensive, and more effective, but liver function must be monitored closely.^ieng

RESUMO

From 1986 to 1994 we treated 26 patients of aplastic anaemia between 6 to 61 years age group with ATG/ALG, Methylprednisone and Oxymethalone. Five had very severe aplastic anaemia, 16 had severe and 5 nonsevere disease. Disease was associated with hepatitis in 5 patients and with pregnancy and drug use in 2 patients each. In others no cause could be ascertained. A total of 31 courses of treatment were given (range 1-3 courses per patient). Nine patients had complete response (34.62%) and 3 had partial response (11.54%) with an overall response rate of 46.16%. Four patients died within 2 months of starting the treatment. The median follow up was 24 months (range 6-102 months) with an overall survival probality of 45% at 2 yr. At the time of evaluation 12 patients have died, 9 are alive disease-free and 5 are alive with disease. The side effects associated with therapy were tolerable and did not require cessation of therapy in any patient. We conclude that ATG/ALG with Methylprednisone and Oxymethalone is beneficial to significant number of patients with aplastic anaemia.

RESUMO

We reported a rare case of pancytopenia caused by allopurinol. A 61-year-old man was first admitted in May 1993, because of thrombocytosis. He had suffered from chronic glomerulonephritis. He was administered allopurinol for hyperuricemia from March 1993. On first admission the laboratory findings revealed leukocytosis (10,100/microliter) and thrombocytosis (971 x 10(3)/microliter) in the peripheral blood. Myelofibrosis was strongly suspected due to increased number of MgK and reticular fiber in the bone marrow. Two months later, he readmitted due to pancytopenia (WBC 1,300/microliter, Hb 6.2g/dl, Plt 10 x 10(3)/microliter). His bone marrow showed markedly hypocellular. Because we suspected that pancytopenia was induced by allopurinol, we discontinued allopurinol and administered oxymetholone, G-CSF, and EPO, WBC, RBC, and platelet count had been recovered about one and half months later. In vitro co-culture indicated that CFU-G, E, and Meg in the bone marrow cells after recovery from pancytopenia were markedly suppressed in the presence of patient's serum and oxipurinol. Pancytopenia due to allopurinol was reported to be rare, and some authors showed that it will sometimes be fatal. Because pancytopenia of this case had been recovered in a relatively short time with cytokine therapy, it was thought to be effective for pancytopenia due to drug like this case.

RESUMO

Thirty male and 27 female patients were treated at the University College Hospital, Ibadan, over a 20 year period (January, 1971 to December, 1990) for aplastic anaemia. Age range was three months to 52 years with a median of 19 years. In 26 patients the aplasia could not be linked with a particular cause. Most patients in this category were students in secondary and tertiary institutions, office workers and casual labourers. Nineteen patients were automobile and factory workers who are exposed to lead while two were dealers in petroleum products. In two patients aplasia was linked to chloramphenicol ingestion while in three, the aplasia linked to the use of hair dye. Another three linked the aplasia to a past history of viral hepatitis. One patient had congenital aplasia of the marrow and one was a radiographer. Treatment included oxymethalone 100 mg given three times daily (tds) or intramuscular (i.m.) Durabolin 500 mg weekly. When these drugs were unavailable prednisolone 60 mg daily was administered. No patient had the benefit of bone marrow transplantation (BMT) or the superior drugs, e.g. anti-thymocyte globulin and cyclosporin A. This might have contributed to the poor prognosis as revealed by the survival pattern in which 24 patients died within six months of diagnosis while 19 survived 12 months. Seven patients died within 18 months and four others died within three years. Three patients were alive five years after presentation. Death generally resulted from complications of the aplastic anaemia with gastro-intestinal bleeding, cerebro-vascular accidents and overwhelming infections.

RESUMO

Forty-eight patients with refractory anemia (RA) were retrospectively analyzed for their prognosis and subclassified into three groups: 12 patients with hematological improvement (A), 23 patients with no changes (B), and 13 patients with progression to RAEB or acute leukemia (C). For all patients, the median survival were 49.2 months, and the rate of leukemic transformation was 16%. The median survivals were 60.6, 32.1, and 17.9 months, respectively, for groups A, B and C. The factors indicating poor prognosis were low reticulocyte counts, low neutrophil alkaline phosphatase activity, low% red cell utilization, high M/E ratio, high blast percentage in the bone marrow and cytological abnormalities in the granulocyte and megakaryocyte series. By using multiple discriminant analysis, we obtained a formula for the prognostic estimation with a discrimination probability of 62.5%. This formula could predict either the patients with good (Y greater than 0.85) or poor (Y less than 0.59) prognosis, and might be useful to select the treatment for this intractable anemia at the time of diagnosis.

RESUMO

Three patients with familial antithrombin III (ATIII) deficiency, who also have histories of thromboembolism, were treated with oxymetholone in combination with warfarin. Thrombolysis was observed in one patient with acute thrombosis of inferior vena cava during the oxymetholone and warfarin therapy. No further thromboembolic episodes occurred in these patients after initiation of warfarin with or without oxymetholone. The levels of plasma ATIII, alpha 1-antitrypsin, plasminogen and Cl-inactivator were significantly increased in all patients after the introduction of oxymetholone therapy. This suggests that oxymetholone augments anticoagulant and fibinolytic activity. Hence we consider that oxymetholone in combination with warfarin may be possible thrombolytic therapy in patients with familial ATIII deficiency.

RESUMO

In a cooperative trial, 99 patients with refractory anemias were treated according to a standard protocol consisting of successive administration of prednisolone (PSL), 1 alpha hydroxyvitamin D3 (D3) and androgens. The primary objective of this protocol was to ameliorate peripheral cytopenia and to assess the value of the 3 drugs, claimed to be of some value, in the management of patients with refractory anemias. In principle, patients were initially treated with oral PSL 40-60 mg/day. Patients not responding to PSL within 4 weeks had an 8-week trial of D3 starting with 1 microgram/day, increasing to 3 micrograms/day. Those not responding to either of the two were given AS. Although the number of evaluable courses is limited as yet for each drug, the preliminary results suggest 1) a slight to moderate increase in hemoglobin in 20-25% of patients on PSL, 2) a partial increase in granulocyte and/or platelets and a reduction of marrow blasts in 10-20% of patients during the administration of D3 and 3) the effects are poorer in cases of severe cytopenia. In addition, the improvement was mostly transient. The treatment was well tolerated in the majority of patients.

RESUMO

To compare the erythropoietic effects of nandrolone decanoate, testosterone enanthate, oxymetholone, and fluoxymesterone, we performed a randomized clinical trial in patients with anemia who were receiving maintenance hemodialysis (the women were not given testosterone enanthate). After a control period of at least two months, patients received one of the drugs for six months and then returned to control status; a second and third drug were administered in a similar fashion. Seventy-seven patients completed the first drug period, 56 the second, and 35 the third. The response to nandrolone and testosterone enanthate, the two drugs given by injection, was clearly superior to the response to oxymetholone or fluoxymesterone, given by mouth, in terms of the percentage of patients responding and the mean rise in hematocrit. Approximately half the patients had an increase of at least 5 percentage points in hematocrit after an injectable androgen was given; more than half the women responded. Patients who required transfusions regularly and those who had bilateral nephrectomies did not respond.
